In this part, there are 2^3 paths which produce MATH, because, at every letter we can either go up or right, and there are 3 places where we make the choice.It's the same for the other 3, so it's 32 total, but, because we counted each straight path twice, we subtract 4 to get the number of possible ways to spell MATH to be 28.

Draw the grid and letters and write a 1 over the M. There's only one M so all routes start there.

Now go to an A. There are 4 of these so write a 1 over each. (see picture)

Now to go to a T. I've just shown the ways to get to one of the Ts. You can go up then right, or right then up so I've written a 2 over that T. Do the same for the other Ts.

Now how can you get to an H from a T? Work that out and write the correct number over each H. Add them up and there's your answer.

EDIT: I'm getting a lot more than 16.

I'm sure there's a way to be sure (this isn't really my area of expertise) but just a cursory attempt at a brute force solution seems to suggest to me that 16's a pretty good answer.]]>http://www.mathisfunforum.com/profile.php?id=847732013-09-29T20:39:44Zhttp://www.mathisfunforum.com/viewtopic.php?pid=285816#p285816I do not know yet, I have not worked on the problem. I am busy with the other ones.

But a cursory examination yields at least 16 so I would think 12 is incorrect.
